Do we have performance comparison between both implementation?
Thanks

Hi all:
We are implementing qemu official vhost-user interface into DPDK vhost library, so there would be two coexisting implementations for user space vhost backend.
Pro and cons in my mind:
Existing solution:
Pros:  works with qemu version before 2.1;  Cons: depends on eventfd proxy kernel module and extra maintenance effort Qemu vhost-user:
               Pros:  qemu official us-vhost interface;     Cons: only available after qemu 2.1
